실험 절차
5-Bromo-pyridin-3-carbaldehyde (15.0 g, 80.6 mmol), malonic acid (18.9 g, 181.4 mmol), and piperidine (6.6 mL, 66.9 mmol) were added to pyridine (48.9 mL). The reaction mixture was stirred at 100° C. for 1 hour, concentrated under reduced pressure, and then distilled water was added thereto. The mixture was filtered and then the resulting solid was dried under reduced pressure to give 28.4 g of the titled compound as a white solid.
